Re: Powerpoint graphics filters

Ge

the nature of my s/w means i have no control and very little knowledge over
the powerpoint installation.

My software always tries JPEG first, if that fails it tries PNG and if that
fails it reports an error. In the past i've tried GIF and BMP also but
discovered that if it was going to fail on JPEG it will always fail.

I believe the problem is intsallation specific in that if it's going to fail
(and remember on 49 out 50 PCs it works just fine) it will always fail...
for every ppt file.

The link you provide suggests that .export() can fail if embedded images in
the slide are too large? I am sceptical - in my testing and with other
customers i have exported some VERY VERY large embeded images.
But I suppose it is possible that that the failing PCs have exceptionaly
large images embedded in all their slides. Is there a way to automate
decreasing the size of all embedded images within a ppt? I know there is a
menu option but i never found a way to automate that.

The automation is normal COM ; no firewalls or .Net remoting.

Hello Nigel,

From your post, my understanding on this issue is: you want to know
whether
graphics filters are optional in PowerPoint installation and why your
application crashes on Slide.Export() sometimes. If I'm off base, please
feel free to let me know.

For your first question, some Graphics filters are optional in PowerPoint
installation according to the kb article:
http://support.microsoft.com/kb/212271/. If you are using Microsoft Office
2003, you will find the options of Graphics filters in Office 2003 setup
application -> Choose advanced customization of applications -> Office
Shared Features -> Converters and Filters -> Graphics Filters. The options
include the import of EPS, CGM, CDR, WPG, PNG, PICT, GIF, and JPEG. But
most of the filters are native (built-in) to Microsoft Office and do not
require a separate filter to be installed.

To verify whether a graphics filter has been installed, please go to
C:\Program Files\Common Files\Microsoft Shared\GRPHFLT. In the directory,
there are several FLT files representing the corresponding graphics
filters
(see: http://support.microsoft.com/kb/235928). For instance, if
GIFIMP32.FLT is the graphics filter for GIF.

For your second question, we could first verify if the correct graphics
filter is available on the computers that encounter the errors.
As to those computers, I wonder whether your application crashes for all
the export image types (GIF, JPEG, etc) and all the powerpoint files? As
Steve said, a corrupt PPT file might cause errors on exports.
http://support.microsoft.com/kb/279238/en-us
Does it work if you directly save the presentation as gif or jpeg in
File->SaveAs command?
Do the powerpoint slides contain images? (see this issue which is caused
by
the image size:
http://groups.google.com/group/microsoft.public.windowsce/browse_thread/thre
ad/f549e4c2f6c7c225/42a3b34dc9663a57?lnk=st&q=remote+procedure+call+failed+p
owerpoint&rnum=2&hl=en#42a3b34dc9663a57)
Does your application access some remote services and is it possible that
the firewall setting caused the problem of 'remote procedure call failed'?

Please let me know the information above so that I can provide further
assistance on this problem. I am looking forward to your reply.

Sincerely,
Jialiang Ge (jialge@xxxxxxxxxxxxxxxxxxxx, remove 'online.')
